Two real tram clips: "likely authentic", and still graded C

Trams at the same Melbourne stop, recorded a few moments apart on two phones. Both clips are real.

• Android phone.
• iPhone.

What changed

• Nothing looked generated. Both clips read "likely authentic" at 15%.
• Both still graded C. The check samples 25 frames across the clip. On a steady shot seven or eight seconds long, neighbouring samples look almost identical, which is what a clip padded with copied frames looks like.
• One extra flag. The Android clip also showed one sudden jump between two frames. Neither finding is a sign of AI.

What the report said: "likely authentic" at 15% for both, and Authenticity C ("moderate risk") for both.

"Likely authentic" means nothing in the sampled frames looked generated, not that a clip is proven real. Read the findings, not just the letter.
